About Washington DC

Washington, D.C., formally the District of Columbia and commonly referred to as Washington, "the District", or simply D.C., is the capital of the United States. On July 16, 1790, the Residence Act approved the creation of a capital district located along the Potomac River on the country's East Coast. As permitted by the U.S. Constitution, the District is under the exclusive jurisdiction of the United States Congress and is therefore not a part of any U.S. state.

Washington, D.C., had an estimated population of 632,323 in 2012, the 25th most populous place in the United States. Commuters from the surrounding Maryland and Virginia suburbs raise the city's population to more than one million during the workweek. The Washington Metropolitan Area, of which the District is a part, has a population of 5.7 million, the seventh-largest metropolitan area in the country.

Local weather patterns

Washington is in the humid subtropical climate zone (Köppen: Cfa) and exhibits four distinct seasons. Its climate is typical of Mid-Atlantic U.S. areas removed from bodies of water. The District is in plant hardiness zone 8a near downtown, and zone 7b elsewhere in the city, indicating a temperate climate.

Spring and fall are warm, while winter is cool with annual snowfall averaging 15.5 inches (39 cm). Winter temperatures average around 38 °F (3.3 °C) from mid-December to mid-February. Summers are hot and humid with a July daily average of 79.8 °F (26.6 °C) and average daily relative humidity around 66%, which can cause moderate personal discomfort. The combination of heat and humidity in the summer brings very frequent thunderstorms, some of which occasionally produce tornadoes in the area.

Blizzards affect Washington on average once every four to six years. The most violent storms are called "nor'easters", which often affect large sections of the U.S. East Coast. Hurricanes (or their remnants) occasionally track through the area in late summer and early fall, but are often weak by the time they reach Washington, partly due to the city's inland location. Flooding of the Potomac River, however, caused by a combination of high tide, storm surge, and runoff, has been known to cause extensive property damage in Georgetown.

The highest recorded temperature was 106 °F (41 °C) on July 20, 1930, and August 6, 1918, while the lowest recorded temperature was −15 °F (−26 °C) on February 11, 1899, during the Great Blizzard of 1899. During a typical year, the city averages about 37 days at or above 90 °F (32.2 °C) and 64 nights at or below freezing.
